-### Remove support for deployableFeature option
+### Tycho 5 Migration guide
+
+#### Remove support for deployableFeature option
 
 The deployableFeature option will create "standard eclipse update site directory with feature content will
 be created under target folder" but we already removed site-packaging from Tycho for a while, if one wants to
 archive similar a category.xml with eclipse-repository packaging gives much more control and power to the user.
 Alternatively the new `mirror-target-platform` mojo can be used.
 
+#### How Bundle-Required-Execution-Environments are taken into account
+
+Before a BREE (Bundle-Required-Execution-Environment) was sometimes incorrectly ignored and overridden by the running JVM.
+This is now fixed but can lead to build failures in some circumstance, for example if your bundle uses a lower execution environment as its dependencies.
+
+There are the following options:
+
+1. Update the BREE to match the ones of your dependencies as this reflects the actual requirements your bundles has.
+You can use the new `update-manifest` mojo for that purpose.
+2. If you still want to taget older BREE at *compile time*, you can set the BREE in your target configuration or target platform file to express the *runtime requirements* you are targeting.
+
